All things not Heartbleed

We were talking yesterday that with the Heart Bleeds issue front and center, what about the "everything else" factor?

With everyone so focused on this one issue, coupled with the knowledge that *lots* of folks still have XP and in the all the OpenSSL excitement might not have patched.  In particular, the horde of XP machines we call ATMs would be a particularly good target this week (or any other week until they get updated really).  So please folks, let's do what we can on the OpenSSL side, but keep the needed focus on other areas too!

Mark's story yesterday on OpenSSL "check" sites makes the great point that these sites can be collecting information as well as giving you info.  Keep in mind that we expect to see some bogus sites pop up to - I'd expect to see some fake check sites distributing malware if we don't see them already

How about SSL and other site issues that aren't vulnerable to Heartbleed?

As I'm assessing client sites and products for Heartbleed, I'm taking the time to do a more complete (but still quick) assessment.  So the client gets a list of:

  • sites that have self-signed certs
  • broken cert chains
  • sites that allow a less than desireable SSL Encryption level
  • and so on, you get the idea

In short, all those SSL things that were in the last several assessment reports, but were never fixed for some reason.  Folks have the perception that "SSL is hard", so I often see admins avoid anything changing anything that affects it, even when it's called out in a security assessment report.  But this weeks focus on SSL is forcing these issues into the light of day, and allowing us to get a lot of them resolved.

I tested my home server with regard to Heartbleed. I saw that my Qualys score was reduced because of support for SSLv2, so I looked up a Microsoft KB article on how to turn that off--dead simple--there's a fix-it app to do it!
So--test for Heartbleed, but consider other remediation steps while looking.
